Notes on the cars:

Brabham BT23C [5] (Jochen Rindt): New to Winkelmann Racing for Jochen Rindt to race in F2 in 1968, winning four of his first seven races. Driven by Vic Elford at at Monza in June and crashed. The car was rebuilt on a new chassis and Rindt won two more races later that year. To Ecurie Ecosse and raced by Graham Birrell in F2 in 1969. Ecurie Ecosse and Birrell had a BT30 for 1970 but the BT23C was raced in a libre at Ingliston in May when it was crashed. Sold in July to Stanley Robinson who fitted the engine, gearbox and suspension to the Unipower GT Group 6 car he raced with John Blanckley. The BT23C chassis was repaired some time around 1972 and sold to Joe Applegarth (Houghton-le-Spring, County Durham) who built it up using parts from BT23C/16 and fitted a pushrod Ford engine for Monoposto racing. Raced by Applegarth from 1973 until the end of 1977, competing in around 130 events, and then retained after Applegarth retired. Sold by him to Joe Willenpart (Scheibbs, Austria) in 2010.

Lotus 48 [R1] (Jackie Oliver): Noted as the chassis number of Watson's Lotus 48 by Race Report at Thruxton 1969 and L'Amie's at Vallelunga 1969.

Brabham BT23C [8] (Kurt Ahrens): New to Kurt Ahrens (Braunschweig, Germany) and raced by him in F2 in 1968 under the Caltex Racing banner. Sold to Bernd Terbeck (Hiltrup, Germany) and run as part of the Montan Racing Team in F2 in 1969 and 1970. Then unknown in 1971 and 1972. Former Mini racer Graham Cooper (Sedgley, Worcestershire) raced his "newly acquired Brabham BT23C" in a sprint at Curborough in March 1973. This car was sold by Cooper to Richard Churchley (Hampton-in-Arden, Warwickshire) and run by him in sprints in 1975 with a Ford twin cam and then in 1976 with a 1600cc Hart BDA. From Churchley to Bill Morris who wanted the engine for his Ensign and sold the rest of the car to Robin Darlington in early 1977. Then to Les Aylott (Oakham, Rutland) and David Knowles, fitted with Aylott's turbcharged 1600cc BDA engine by by June 1977, and raced in 1977 and 1978. Advertised from Oakham in April 1981. Then unknown until raced by Peter Rogers (High Wycombe, Buckinghamshire) in the HSCC Bradburn & Wedge Pre-71 series in 1984 with a BDA engine. (Possibly the car raced by Jon Bradburn in late 1983.) Raced by Rogers until 1987. Sold by Rogers' father Sir John Rogers to David Brown (Ashford, Kent) in 1999 and raced by him in the HSCC Classic Racing Cars Championship. Raced regularly by David Brown (Ashford, Kent) in HSCC events until sold to Graham Adelman (Free Union, VA) in 2014.

Tecno 68/F2 [T00 290?] (Pedro Rodriguez): After ther failure of the Protos F2 project, Ron Harris Racing bought a pair of Tecnos with the first of these debuting at Crystal Palace 3 Jun 1968 where it was raced by Pedro Rodriguez. Used later in the season by team drivers Richard Attwood, Eric Offenstadt and Jonathan Williams. Taken to the Argentine Temporada at the end that year where it was allocated to Carlos Marincovich. Subsequent history unknown but if it is correct that T00 288 went to Britain for libre racing and that T00 296 went to Daniel Rouveyran for French hillclimbs, then T00 290 must be the "ex-Harris" car that went to Patrick Champin for 1969 and then to Max Bonnin for 1970.

Brabham BT23C [7] (Piers Courage): New to Frank Williams Racing Cars for Piers Courage to race in F2 in 1968. Also raced by Jonathan Williams to win at Monza in June. To Roly Levis (New Zealand) and raced in the 1969 Tasman series and at Singapore, Batu Tiga and Fuji in the following months. Raced in the opening rounds of the 1969/70 New Zealand season and then sold to Baron Robertson who raced it Pukekohe in early December. Levis then tested the car for Robertson in practice for the Bay Park International at the end of December but crashed heavily at Rothmans corner, effectively writing off the car. Robertson acquired a replacement frame from Racing Frames in England and built a car which used a different chassis number. The original BT23C/7 frame was rebuilt as a Formula Ford and raced by Peter Haskett in the 1973/74 NZ season. This car found its way to Martin Smith in the UK in the late 1980s after which it was restored to BT23C specification. Then unknown until acquired by Bobby Rahal in the US and extensively rebuilt by Phil Simkin some time before 2004. With Justin Segel (West Bloomfield, MI) in 2003. For sale in 2006 when said to have been owned by Tom Claridge (Fremont, CA). To Ted Wentz (Villanova, PA) 2008.

Tecno 68/F2 [T00 288?] (Richard Attwood): One of a pair of Tecnos run by Ron Harris Racing from June 1968 onwards, replacing the team's unsuccessful Protos-FVAs. Used by team drivers Pedro Rodriguez, Richard Attwood, Eric Offenstadt and Jonathan Williams. Taken to the Argentine Temporada at the end that year where it was allocated to Carlos Reutemann. When Reutemann moved to race a Brabham BT23C at the last round, the Tecno was taken over by Oscar Franco. The "ex-Reutemann" Temporada car was later used by John Rae in libre with an Atlantic spec BRM Ford twin-cam. Subsequent history unknown.

Tecno 68/F2 [T00 286] (Silvio Moser): Bought by Charles Vögele for Silvio Moser (Lugano, Switzerland) to race in European F2 and Swiss Championship events in 1968. Also taken to the Argentine Temporada at the end that year. Sold to Roland Binder (Esslingen, Germany) and used in F2 in 1969, 1970 and 1971. According to later owner Oliver Heschl- Gillespie, the Tecno went to Bernd Burger (Rüsselsheim, Germany) and was converted to a Group 7 sports car using a KMW body as the "Burger P3", still with its 1600cc Cosworth FVA. Burger raced it in German national racing 1973 and 1974 after which the rolling chassis was sold to Karl Langjahr (Darmstadt, Germany) who fitted a Porsche engine and raced it in Interserie and national events as a Tecno-Porsche until 1980. Then to Bernd Becker (Idar-Oberstein, Germany) who only wanted the engine. The car continued via Kurt Henn (Idar-Oberstein, Germany) to Christina Berthold (Nürnberg, Germany) who raced it briefly with a new Porsche engine at which point it was sold to the Rosso Bianco Collection (Aschaffenburg, Germany). Sold by the museum in 1999, it passed via an Viennese Porsche dealer to Olivier Heschl-Gillespie (Vienna, Austria) who had it restored by Karl Langjahr to its 1974 specification.

Brabham BT23C [9] (Jonathan Williams): New to Church Farm Racing Team (Pagham, Sussex) for Derek Bell to race in F2 in 1968. Bell moved to the Ferrari F2 team in June 1968 and the car was raced by Jonathan Williams at Hockenheim, by Peter Westbury and Monza and then by Brian Hart for the rest of the season. Advertised in December 1968 and March 1969. Subsequent history unknown.

McLaren M4A [200-18F] (Jo Schlesser): Ecurie Intersport for Jo Schlesser in F2 in 1968 until his death in a F1 race in July. Presumably then the "ex-Schlesser" McLaren M4A raced in French hillclimbs by Jean-Claude Fontès (Bayonne, France) in 1969, by Hughes Hazard in 1970 and by Roger Rivoire in 1972. Then unknown until restored by an unnamed German owner in 1990. Appeared in various auctions between 1997 and 2005, in the midst of which Paul Dudley (and Steve Worrad) raced it in historic racing in 1999 and 2000. Sold at Bonhams & Brooks' Silverstone auction in September 2001 to an unknown owner who restored it in 2004 and then sold it via Bonhams Silverstone auction in July 2005. With Lindsay O'Donnell (Christchurch, NZ) in 2005 and raced for him by Ken Smith at Eastern Creek in December 2006. Still with O'Donnell in 2009.

McLaren M4A [200-19F] (Guy Ligier): Ecurie Intersport for Guy Ligier in F2 in 1968. The team was disbanded after Schlesser's death in a F1 race in July. If Schlesser's regular car went into French hillclimbs, then 200-19 is likely to be one of two cars acquired from the team by Pierre Bardinon (Aubusson, France) and would be the car raced by Bardinon at the Mont-Dore hillclimb in August 1968. These two cars were then traded by Bardinon to Franco Sbarro (Grandson, Switzerland) and one was sold to Georges Schäfer (Geneva, Switzerland) for use in French hillclimbs and Swiss national events in 1971, as well as a single F2 race. After crashing this car, Schäfer bought Sbarro's second car. Then unknown until offered for sale by Hans Peter (Switzerland ) in August 1990. A car with this chassis number was in the Brooks Monaco auction in 2000 when it was said to be "unraced since 1968". Also at this time, Auto-Salon-Singen (Singen, Germany) advertised a pale yellow "ex-Schlesser" McLaren M4A that was said to be unraced since 1968. Subsequent history unknown

Brabham BT23C [11] (Alan Rees): New to Winkelmann Racing for Alan Rees to race in F2 in 1968 but also raced by Gerhard Mitter at Hockenheim in October. To Bill Ivey for 1969 and entered for him in F2 races by Paul Watson Racing Organisation (PWRO). To Brian Cullen (Limerick, County Limerick, Ireland) in August 1969 and he raced it in a F5000 race and in libre in 1969, in European F2 events in 1970, and at Bogotá in early 1971. Entered by Irish Racing Team for Lingard Goulding at Mondello Park in July 1971 and then maybe the BT23C raced by Ted Shanahan (Dublin) over the next two months and also possibly the BT23C raced by Roy Courtney (Lisburn, County Antrim, Northern Ireland) in local clubmans/club specials racing in 1972. To Harold McGarrity (Belfast) for 1973 and raced in Formula Ireland with a 1.6-litre Holbay engine. To Paddy Heron for 1974 and raced in clubmans and in Formula Atlantic. For sale from Glengormley in 1975 and entered by Belfast car dealer Noel Crymble for Chris Stanfield to race at Kirkistown a couple of times until the Holbay pushrod engine blew up. Next seen when bought from Ireland by Mark Raymont who still had it in the late 1980s with a Holbay engine and Hewland Mk 8 gearbox. Sold to Steve Worrad of Maverick Motorsport around 2002 and restored by him. For sale by Maverick in 2004 and sold the following year via the Bonhams auction at RAF Hendon to Joe Willenpart (Scheibbs, Austria).

Merlyn Mk 12 [109?] (John Cardwell): New for Bob Gerard's quasi-works F2 team in 1968, and raced early in the season by John Cardwell. This car was updated to MK 12A specification for 1969 and run alongside Gerard's Brabham BT23C for Robin Widdows and others. Advertised by Gerard Racing in January 1970 but not seen again until Pete Tester ran it in a libre race at Lydden in early 1973. Used by Peter Bull (London) in sprints that summer, by which time it had a BRM engine of some sort, and then advertised by Bull in September with a 1600cc Ford twin cam engine and FT200 gearbox. Bull bought a Brabham BT30 for 1974 and the later history of the Merlyn is unknown.

McLaren M4A [200-15F] (Robin Widdows): This number is given for a Formula 2 car built up by Chequered Flag in June 1968 for Robin Widdows after he crashed his regular car at Crystal Palace. As this chassis number is lower than that of his regular car, it suggests that the car may have been sitting around in kit form, opening up the possibility that several other McLarens with similar numbers may have been completed out of order. Likely to have been one of the four M4As advertised by Chequered Flag at the end of 1968. Sold to Charles Kirkbride (Chatham Hills, NJ) and fitted with a 2.5-litre Climax engine for Formula A in NEDiv events from 1969 to 1972. Then unknown until purchased by a New Jersey owner in 1984 and retained by him until advertised on race-cars.com. To Richard Griot (Seattle, WA) in late 1990s or early 2000s.

Brabham BT23 [3] (Xavier Perrot): Motor Racing Developments entry for Frank Gardner in 1967. To Squadra Tartaruga for Xavier Perrot (Zürich, Switzerland) to race in F2 in 1968. Retained early 1969 but damaged at Nürburgring 27 April by a Porsche landing on top of it. Sold via Jo Siffert in 1969 to Jacques Joliat (Porrentruy, Switzerland) who raced it in French and Swiss hillclimbs in 1970 and 1971, before replacing the FVA with a FVC for 1972. Unknown in 1973 and 1974, then to Michel Salvi (Malbuisson, France) and raced with a 1300cc Renault Gordini engine in 1975 and 1976. To Alain Ribager (Mulhouse, Alsace, France) in 1977, and raced by him until 1979, then very probably the Renault-engined BT23 raced by Jean-Pierre Mutel in 1981 and 1982. Found by Gérard Gamand in 1984 near Valence, France with March bodywork but still with a Renault engine. To Michel Champelovier 1989 then 'Hollinger' then Thierry De Mortier by 2006. To Max Pearson (Queensland, Australia) 2010.

McLaren M4A [200-22F] (Frank Gardner): This number is given for a Formula 2 car entered by Chequered Flag for Graeme Lawrence early in the 1968 season, then Frank Gardner and then Mike Walker. Likely to have been one of the four M4As advertised by Chequered Flag at the end of 1968.

Brabham BT23C [4] (Chris Lambert): New to London Racing Team for Chris Lambert to race in F2 in 1968. Crashed during the F2 race at Zandvoort on 28 July 1968 and Lambert was killed. It is believed that the car was broken up.

Brabham BT23C [6] (Max Mosley): New to Max Mosley and entered for him by London Racing Team and then by Frank Williams Racing Cars in F2 in 1968. Sold to Peter Parnell (Bulawayo, Rhodesia) and raced in South African events in 1969. Then to Arnold Charlton (Sandton, Johannesburg, South Africa) for 1970 but crashed in practice at Roy Hesketh in March. Advertised as "recently rebuilt" and "immaculate" by Charlton in August 1970. Reported as sold back to the UK late in the year after repeated FVA problems. Just one week after Charlton's adverts stopped, D&A Shalls (Stratford, east London) advertised a BT23C. Some time in late 1971 or early 1972 John Hardesty bought a BT23C from an east London dealer who told him that it had come back from South Africa. Chris Choat prepared the car for Hardesty and also raced it in libre racing. In October 1972, Choat was entered for a libre race at Silverstone in a green Brabham BT23C and he was mentioned racing it at Silverstone in March and July 1973. It can be assumed he was at other races during that period but too far down to be mentioned in reports. According to Hardesty, Choat destroyed the car when he crashed at Woodcote corner and bent it round a post. The car was broken up and the suspension went to Bobby Howlings.

Brabham BT23 [4] (Walter Habegger): Roy Winkelmann Racing for Alan Rees in F2 1967. To Walter Habegger (Oberönz, Switzerland) 1968 for Swiss championship events. To Gérard Pillon (Geneva, Switzerland) 1969 and used in Swiss national events and French hillclimbs. (Although one source gives this as the car of Enzo Corti at Rheims and Albi in 1969, that identification looks highly doubtful.) Crashed at Côte de la Faucille on 7 September and not seen again. In 2009, Walter Habegger recalled that Pillon had an accident in the car and that it was badly damaged.

Brabham BT10 [F2-12-64] (Chris Meek): Mike Costin of Cosworth Engineering bought this car later in the 1964 season and raced it a handful of times with its usual Cosworth SCA engine. It appeared in a libre race with a 1500cc Cosworth prototype engine at Silverstone in June 1965 and then in F3 spec with Cosworth's new MAE engine in September 1965. In August 1966, it appeared again with the prototype FVA F2 engine and was Cosworth's test car for the FVA in 1967. In 1968 it was sold to Bill Jones who entered it in F2 for Chris Meek. It then went to John MacDonald (Hong Kong) for 1969 and was raced across for the next three seasons, firstly with the FVA engine and later with a Ford twin cam when four-valve engines were banned. Retained by MacDonald until 2007 when he advertised it.

Brabham BT23 [7] (Werner "Noddy" Lindermann): To Gerhard Mitter (Germany) and raced in selected F2 events in 1967. Then entered by Mitter Tuning for Werner Lindermann in 1968. Retained by Lindermann and entered by Montan Racing Team through the 1969 season, returning in 1970 for the team's second driver Helmut Gall. Last seen at Hockenheim on 12 April 1970 but believed to have been destroyed some time later.

Lola T60 [SL60/4] (Brian Cullen): First appears with Eric Offenstadt late 1965 and raced in F2 with BRM power in 1966. Bought by Robs Lamplough (London) in 1967 and sold on to Brian Cullen for Irish 1600cc class racing in 1968 and 1969. Then sold to the US, where it ws advertised by Sport Car Service (Vandalla, Ohio) in May 1970. Likely to be the T60 advertised by R.H. Kulaas (Fairborn, Ohio) five months later. Bought by Gerry Hudson (Galva, Kansas) in 1970 and raced in SCCA Formula B and then Formula C over the next few years. Still with Hudson in 2013.
Subsequent history unknown.

Brabham BT18 [BT16 F2-33-65] (Paul Blum): New to Walter Habegger (Oberönz, Switzerland) in March 1966, fitted with a 1600cc Lotus-Ford twin cam and entered by Midland Racing Team for Habegger in Swiss national events. To Bruno Frey (Horw, Switzerland) for 1967 and raced in Swiss events plus selected Formula 2 races, still as part of Midland Racing Team. To Paul Blum (Frick, Switzerland) for 1968, and again used in Swiss national events and run for him by Midland Racing Team. To Kurt Buess (Gelterkinden, Switzerland) for 1969 and 1970, then to Georges Hedinger for 1971. The car went to Fritz Messerli for 1972 but was stored until sold to Raphael Weber in 2006. Weber sold it in June 2011 to Gerald Ludwig (Krefeld, Germany), who restored it to original condition. Run for the first time at the Brabham revival meeting at Reims, France, in September 2016.

Cooper T72 (Hartmut Hoheisel): Hartmut Hoheisel appeared at the June 1967 Rhine Cup in a very curious car. The chassis was a 1964 Cooper T72 said to have been raced previously in F3 by one James Etherley. The engine consisted of a Ford Cortina block with a twin-cam head designed by Hoheisel with four valves per cylinder and Lucas fuel injection. A Porsche 911S gearbox complex a unique specification. Nothing is known of his performance that day
